Abstract: PURPOSE:To high accurately determine action timing of engine ignition or the like by a simple constitution, in the case of an engine control device for a ship propulsive machine. CONSTITUTION:An output time difference T0 between a reference crank angle signal of a pulser coil and a crank angle signal of a crank angle signal generator is measured. In the vicinity of the point of time of outputting the reference crank angle signal of the pulser coil, an output value of the crank angle signal generator is used to measure crank rotational time t1 in a fixed crank angle range theta1, and a crank angle difference theta0 corresponding to the difference T0 is calculated based on the time t1 in the range theta1. An action timing arithmetic starting crank angle theta0+theta2, which is an origin for arithmetically controlling this ignition timing theta just before preestimated action timing theta by a fixed action crank angle theta4, is determined relating to a reference crank position. The output value of the crank angle signal generator is accumulated, and from the point of time the accumulated output value reaches theta0+theta2, crank rotational time T4 corresponding to the action crank angle theta is calculated based on the time t1 in the range theta1 to actuate engine ignition timing at reaching time of T4.
